I am a research scientist working in the Cloud Processes Research Group at Lawrence Livermore National Laboratory. I study the Earth’s energy budget, specifically the role of clouds in reflecting solar radiation incident on the planet (a cooling effect) and in reducing the infrared radiation emitted by the planet (a heating effect). I am particularly interested in how cloud properties change as the planet warms due to greenhouse gases, and whether clouds act as positive feedbacks that amplify warming, or negative feedbacks that diminish warming. To investigate these processes, I use theory, observations, and global climate models.
